How does the camera take pictures at night?
Night photography can use one exposure method or multiple exposures. One exposure is a long exposure using B-gate or T-gate. Multiple exposure is the first exposure when it is not completely dark, and the outline of the scene is taken. Then, when the sky is dark and brightly lit, a second exposure is made.
If the focus of the scene is not clear, so that the light presents a circular shooting effect, then it will produce interesting effects when shooting city lights. Make sure you are in manual focus mode when composing, and then adjust the focal length.
Night photography can use one exposure or multiple exposures. One exposure method is to fix the camera with a tripod, to control the opening and closing of the shutter with long exposure and cable release. Multiple exposure method is to make more than two exposures on a negative, which is often used in outdoor lighting shooting at night.
Therefore, when shooting night scenes, it is suggested to use different white balance settings in the same scene as much as possible. In addition, saving photos in RAW format can make it easier for photographers to adjust the white balance as needed later.

1. One of the common methods for shooting night scenes is long exposure (the shutter value is as slow as 10 second, 30 seconds or several hours), which can be used to shoot car tracks, star tracks, waves, etc.
2, shutter shock absorption. When the camera is placed on a tripod or other stable place to shoot, in order to avoid the photo confusion caused by the vibration caused by pressing the shutter by hand, the shutter is usually operated by releasing the cable; If there is no "cable release", you can use the "delayed shooting" function of the shutter instead, and it is better to set the delay time above 5 seconds. Iso sensitivity.
3. Tip 1: It usually takes a long time to take a night view with your own tripod, so the camera should be hidden to take a clear picture. In order to avoid damaging the photo effect by vibration, it is best to use a tripod to reduce shaking.
4, Canon SLR shooting night scene method: use M file shooting. In the dead of night, manual mode is more convenient to adjust. ISO settings. Use a lower ISO, controlled between 100-500, to reduce the noise of the picture, and generally use a lower ISO when shooting at night to ensure the picture quality.
It is recommended to shoot in RAW format, which is helpful for editing photos better. Select the shooting location. Before shooting at night, please check the situation, find a suitable shooting point and evaluate the illumination of the object. If you plan to photograph buildings, be sure to analyze road traffic and street traffic.
Photography lights and flashlights must be added to make them bright and clear. When it is possible to take clear photos with iPhone at night, generally speaking, the effect will be better when there is more light in the photos.
Hand-held shooting. There is a "safety shutter" limit for hand-held shooting. If the shutter is too slow, it is easy to shake the picture. At this time, it is necessary to increase the aperture and increase the sensitivity if necessary. Use shallow depth of field effect to highlight details.
